调用模态实现弹出页面框

function showDivChildDialog(defaults) {
 var options = $.extend( {}, top.option, defaults);
 options.modal = false;
 $.dialog(options);
 $("#divChildDialog").dialog("open");
}
function isExistDynByIDCardNO() {
 var message = '';
 jQuery.validator.addMethod('isExistDynByIDCardNO',
   function(value, element) {
    var flag = false;
    var invyear = $("#invyear").val();
    var idcardno = $("#idcardno").val();
    var povid = $('#povid').val();
    var param = {
     "povfamily.invyear" : invyear,
     "povfamily.idcardno" : idcardno,
     "povfamily.povid" : povid
    };
    $.ajax( {
     type : "post",
     url : "dynPovFamilysAction!isExistByIDCardNO.action",
     data : param,
     async : false,
     success : function(response) {
      var _data = eval("(" + response + ")");
      message = _data.reason;
      flag = _data.success;
      if (!flag) {
       alert(message);
      }
     }
    });
    return flag;
   }, message);
}
